A 1929 book published by University of California Press on the pre-indian burial in Lovelock Cave, Nevada. The mummies were very different from other indian grave sites. From the materials found with them and the mummies themselves. They were much taller, had red hair and different skull shape than the American Indians, much closer to Europeans. A few have theorized that they were decendants of the Solutreans that crossed the Atlantic following the ice sheets.
